Acupuncture is proven to work by thousands of scientific studies

Over the last 50 years, tens of thousands of research studies, including randomized controlled trials and systematic reviews, have been published. They show that acupuncture is an effective treatment for a wide variety of medical conditions.

In 2002, the World Health Organisation (WHO) published a report on acupuncture effectiveness. They identified 31 conditions for which acupuncture was proven to be effective and further 63 conditions for which there was at least some evidence that acupuncture could help.1

In 2017, authors of The Acupuncture Evidence Project, after reviewing thousands of trials, found moderate to high quality evidence of acupuncture effectiveness for 117 conditions out of 122 conditions studied.2 Stephen Janz, one of the authors, concluded:

“It is no longer possible to say that the effectiveness of acupuncture can be attributed to the placebo effect or that it is useful only for musculoskeletal pain”.

In the UK, in 2021, National Institute for Clinical Excellence (NICE) published guidelines on chronic pain management. Acupuncture is one of only four evidence-based treatments recommended for chronic primary pain.3

In their 2021 guidelines ‘Headaches in over 12s: Diagnosis and Management’, NICE also recommend acupuncture for the prophylaxis of tension headaches and migraines.4

Worldwide, 3,809 clinical guidelines make 9,340 positive recommendations for acupuncture. Of these, 5,572 recommendations are made for acupuncture pain relief, and 3,768 recommendations are made for acupuncture treatment of non-pain symptoms.5

Acupuncture helps your body heal naturally

The human body has an amazing ability to heal itself. When we are sick or injured, our bodies produce various healing chemicals to help us recover. Acupuncture needles stimulate specific acupuncture points to activate and reinforce the body’s natural healing abilities.

For example, to relieve pain, acupuncture triggers an increase in the levels of endorphins, your body’s natural painkillers. In contrast, some prescription opioid drugs work by mimicking the action of endorphins. But, unlike acupuncture, opioid drugs are addictive, have side effects and are proven to cause at least 1.5% of deaths in the general population and 20% of deaths in younger adults aged 24-35.6

Acupuncture treatment is safe

Safety studies show that acupuncture, when administered by a qualified acupuncturist, is safe for everyone, including adults, babies and children,7 the elderly, pregnant people,8 patients undergoing cancer treatment9 and people with a compromised immune system.

A systematic review of the safety of acupuncture published in The British Medical Journal in 2021 concluded that:

“Acupuncture can be considered among the safer treatments in medicine. SAEs [serious adverse effects] are rare, and the most common minor AEs [adverse effects] are very mild”.10

The authors of the study highlight that the low incidence of adverse events is linked to a high level of acupuncture training. So patients should ensure that they see only fully qualified acupuncturists.

Acupuncture has lasting effects

Another benefit of acupuncture is that patients often feel long-lasting improvements in their health after completing a course of treatment.

In 2017 large meta-analysis study that included 29 trials and 17,922 patients suffering from chronic pain found that 90% of the benefits of acupuncture were sustained at 12 months when compared to patients who had no acupuncture.11

The lasting effects of acupuncture have been documented in other health conditions, including menopausal symptoms,12 constipation,13 migraines,14,15 irritable bowel syndrome,16 improved AMH hormone levels in patients with Polycystic Ovarian Syndrome (PCOS),17 and more.

This long-term effect is attributed at least in part to acupuncture treatment’s ability to induce neuroplastic changes in the brain. 18 In other words, acupuncture literally rewires your brain to function better. This is something that very few treatments can do.

Acupuncture helps more than one symptom

One of the advantages of acupuncture over other treatments, such as pharmaceutical drugs, is that more than one symptom can be addressed at the same time. For example, patients who have chronic pain often experience depression and sleeping difficulties. Acupuncture can help with all of these symptoms at the same time.

Acupuncture patients have a high level of satisfaction

Acupuncture patients report a high level of satisfaction. For example, in one study, 79% of acupuncture patients found that acupuncture provided at least some help with their primary condition, while 55% reported a great deal of help.19

Acupuncture needles are comfortable

Acupuncture is not only effective, but it is also a comfortable and enjoyable experience. Acupuncturists use very thin needles, as thin as human hair (acupuncture needles 0.12-0.25 vs human hair 0.09-0.12mm). So, you will barely feel them when they are inserted.

Acupuncture can be used alongside other treatments

Acupuncture can be used in conjunction with other treatments. For example, it is often used by patients undergoing infertility or cancer treatments. 

Acupuncture can be used for physical and emotional wellbeing

Acupuncture is not just for people with illnesses. Regular acupuncture users report overall health benefits, including:20

  • Better sense of control over own health
  • Reduced stress and increased relaxation levels
  • Improved sleep
  • Improved emotional wellbeing
  • Increased ability to cope more easily with health problems
  • Improved sense of health and wellbeing
  • Improved relationships with others

Considerations when choosing an acupuncturist

Acupuncture is safe and effective if administered by a fully qualified acupuncture practitioner. In 2020, the World Health Organization updated their recommendations on acupuncture training. WHO recommends that acupuncturists should receive at least 1,568 hours of basic training or 2,468 hours of advanced-level training. This is equivalent to a three years degree level training. 

Acupuncture practitioners’ training should include not only detailed knowledge of acupuncture and Traditional Chinese Medicine but must also cover conventional western medicine theory (such as anatomy, physiology, pathology, biochemistry and diagnostics), as well as medical laws, regulations, ethics and research skills.21


Acupuncture is an evidence-based, safe and effective treatment for a wide range of health conditions. It has been used for over 3,000 years, and its popularity is increasing as more and more people experience its benefits. Acupuncture can be used to treat a single symptom or multiple symptoms at the same time. It can also be used for general wellness. When choosing an acupuncturist, make sure the acupuncturist has received adequate training and is degree-level qualified.
